625f164963 Include internal functions in the observer API 
There are two main motivations to this:
a) The logic for handling internal and userland observation can be unified.
b) Unwinding of observed functions on a bailout does notably not include observers. Even if users of observers were to ensure such handling themselves, it would be impossible to retain the relative ordering - either the user has to unwind all internal observed frames before the automatic unwinding (zend_observer_fcall_end_all) or afterwards, but not properly interleaved.

Make vm_interrupt and timed_out atomic (#8327) 
This is done by adding a new zend_atomic_bool type. The type
definition is only available for compiler alignment and size info; it
should be treated as opaque and only the zend_atomic_bool_* family of
functions should be used.

Note that directly using atomic_bool is complicated. All C++ compilers
stdlibs that I checked typedef atomic_bool to std::atomic<bool>, which
can't be used in an extern "C" section, and there's at least one usage
of this in core, and probably more outside of it.

So, instead use platform specific functions, preferring compiler
intrinsics.

b4285e5546 Ensure vm_spec_handlers exists for all opcodes <= 255 so that user defined higher opcodes do not read outside buffer 
This largely has no effect in practice, but ASAN will complain then.

4543cd32ae Remove JMPZNZ opcode 
While JMPZNZ can avoid execution of a separate JMP opcode in some
cases, it also prevents smart branch optimization, so creating
JMPZNZ may actually have a negative effect. It also adds additional
complexity for optimizations.

Drop JMPZNZ in favor of JMPZ+JMP or JMPNZ+JMP.

Closes GH-7857.
